Mozilla Firefox — свободный браузер на движке Gecko

Mozilla Firefox before 49.0 allows user-assisted remote attackers to obtain sensitive full-pathname information during a local-file drag-and-drop operation via crafted JavaScript code.

The mozilla::a11y::HyperTextAccessible::GetChildOffset function in the accessibility implementation in Mozilla Firefox before 49.0 allows remote attackers to execute arbitrary code via a crafted web site.

Buffer overflow in the mozilla::gfx::FilterSupport::ComputeSourceNeededRegions function in Mozilla Firefox before 49.0 allows remote attackers to execute arbitrary code by leveraging improper interaction between empty filters and CANVAS element rendering.

Mozilla Firefox before 49.0 does not properly restrict the scheme in favicon requests, which might allow remote attackers to obtain sensitive information via unspecified vectors, as demonstrated by a jar: URL for a favicon resource.

Multiple unspecified vulnerabilities in the browser engine in Mozilla Firefox before 49.0 allow remote attackers to cause a denial of service (memory corruption and application crash) or possibly execute arbitrary code via unknown vectors.

The PropertyProvider::GetSpacingInternal function in Mozilla Firefox before 49.0 allows remote attackers to cause a denial of service (out-of-bounds read and application crash) via text runs in conjunction with a "display: contents" Cascading Style Sheets (CSS) property.

Mozilla Firefox before 49.0 allows remote attackers to bypass the Same Origin Policy via a crafted fragment identifier in the SRC attribute of an IFRAME element, leading to insufficient restrictions on link-color information after a document is resized.

Memory leak in Libxul, as used in Mozilla Firefox 3.0.5 and other products, allows remote attackers to cause a denial of service (memory consumption and browser hang) via a long CLASS attribute in an HR element in an HTML document.

Mozilla Firefox before 48.0 and Firefox ESR 45.x before 45.3 preserve the network connection used for favicon resource retrieval after the associated browser window is closed, which makes it easier for remote web servers to track users by observing network traffic from multiple IP addresses.

Heap-based buffer overflow in the nsBidi::BracketData::AddOpening function in Mozilla Firefox before 48.0 and Firefox ESR 45.x before 45.3 allows remote attackers to execute arbitrary code via directional content in an SVG document.
